Differences in the clinical manifestations of sicca syndrome in the presence and absence of rheumatoid arthritis.

In this restrospective study we review the clinical features of patients with the sicca syndrome in the presence and absence of rheumatoid arthritis. All patients were followed at the National Institutes of Health for at least five years after the diagnosis of sicca syndrome was established. Twenty-two patients had sicca syndrome alone, and 21 patients had definite rheumatoid arthritis and the sicca syndrome. Rheumatoid arthritis tended to precede the developement of sicca syndrome. The mean age at diagnosis of sicca syndrome is the same in both groups. No significant differences in serum innumoglobulins, the third component of complement (C3), rheumatoid factor titer and salivary histopathology were found. However, the clinical features were quite distinct. Patients with sicca syndrome alone had a significantly greater frequency of recurrent parotitis, Raynaud's phenomenon, purpura, lymphadenopathy, myositis and renal involvement. The clinical characteristics of these two groups coupled with the known serologic and genetic differences suggest that sicca syndrome alone is a distinct pathologic entity.

Bladder complications in patients receiving cyclophosphamide for systemic lupus erythematosus or rheumatoid arthritis.

The bladder complications of 54 patients treated with oral cyclophosphamide for systemic lupus erythematosus (43) or rheumatoid arthritis (11) were reviewed. During an observation period of 241 patient years, we saw seven cases of acute hemorrhagic cystitis and two cases of transitional cell carcinoma of the bladder. Bladder carcinoma was identified 28 and 60 months after withdrawal of the drug and resulted in the death of one patient. The late-occurring serious toxicities of cyclophosphamide should limit the use of the drug in the treatment of nonmalignant inflammatory rheumatic conditions.

NIH conference. Systemic lupus erythematosus: evolving concepts.

Systemic lupus erythematosus, a disease of unknown cause and protean manifestations, continues to excite substantial investigational interest. These papers bring together recent advances in concepts of its immunopathogenesis, evidence for a major genetic role in the causation of the process, developing systems for the morphologic assessment of its often fatal nephritis, and data from ongoing trials of cytotoxic drugs in its management.

B-lymphocyte alloantigens associated with systemic lupus erythematosus.

We examined B-lymphocyte alloantigens in 41 patients with systemic lupus erythematosus and 184 controls, using a panel of 47 pregnancy serums, and compared reaction frequencies of individual serums. One serum, la-715, reacted with B lymphocytes from 75.6 per cent of patients and 14.1 per cent of controls (Pc less than 0.005, relative risk 18.8). Twenty-eight of the patients were also typed with a panel of HLA-D-related serums from the Seventh International Histocompatibility Workshop, HLA-DRw types assigned, and compared to 490 Workshop controls. Both HLA-DRw2 (57.1 per cent vs. 26.4 per cent, Pc less than 0.004) and HLA-DRw3 (46.4 per cent vs. 22.2 per cent, Pc less than 0.03) were increased in systemic lupus erythematosus. This study demonstrates that select B-lymphocyte alloantigens, which are controlled by genes in the major histocompatibility complex, are present in increased frequency in systemic lupus erythematosus.

The hand in mixed connective tissue disease.

The mixed connective tissue disease syndrome has been described in the medical literature. The clinical and serological characteristics of the syndrome are defined in this paper. The hands of these patients differ from the hands of patients with systemic lupus, rheumatoid arthritis, or systemic sclerosis. In 10 patients there were no erosive changes on radiological examination and all 10 patients had Raynaud's phenomenon. The most striking finding was tightness in the flexors. Mild cases of flexor tightness improved with systemic steroids. One patient with severe flexor tightness required surgical release of adhesions from a chronic inflammatory process of fascia, muscle, and tenosynovium. Biochemical studies showed an abnormal collagen pattern that may be distinct for mixed connective tissue disease.

Influenza immunization in systemic lupus eruthematosus. A double-blind trial.

Forty patients with systemic lupus erythematosus randomly received inactivated bivalent (A/NJ and A/Victoria) influenza vaccine or saline in a double-blind study. During 20 weeks of follow-up, no deterioration in major organ function or increase in disease flares was observed in the immunized group as compared with the group that received saline. Preimmunization antibody titers to A/Victoria were lower in the 40 patients with lupus erythematosus than in age-matched control subjects. Response to immunization, as measured by serum antibody titers, was also lower in the patients with lupus erythematosus, indicating that immune responses must be evaluated on an individual patient basis. Nevertheless, influenza vaccination can be safely carried out in patients with systemic lupus erythematosus.

Increased risk of lymphoma in sicca syndrome.

The risk of cancer was ascertained in 136 women with sicca syndrome followed at the National Institutes of Health (NIH). Seven patients developed non-Hodgkin's lymphoma from 6 months to 13 years after their first admission to NIH. This was 43.8 times (P less than 0.01) the incidence expected from the rates of cancer prevailing among women of the same age range in the general population during this time. In addition, three cases of Waldenström's macroglobulinemia occurred in this study group. Eight patients developed cancers other than lymphoma, similar to the number expected based on the rates prevailing in the general population. Patients with a history of parotid enlargement, splenomegaly, and lymphadenopahy had an increased risk of lymphoma. These clinical conditions did not appear to be early manifestations of undiagnosed lymphoma but rather seemed to identify a subgroup of patients with sicca syndrome with marked lymphoid reactivity, who had a particularly high risk of subsequently developing lymphoma.

Preliminary criteria for the classification of the acute arthritis of primary gout.

The American Rheumatism Association sub-committe on classification criteria for gout analyzed data from more than 700 patients with gout, pseudogout, rheumatoid arthritis, or septic arthritis. Criteria for classifying a patient as having gout were a) the presence of characteristic urate crystals in the joint fluid, and/or b) a topus proved to contain urate crystals by chemical or polarized light microscopic means, and/or c) the presence of six of the twelve clinical, laboratory, and X-ray phenomena listed in Table 5.

Error in anti-DNA antibody radioimmunoassay after gallium scanning.

Significant interference with the accurate measurement of anti-DNA antibodies occurs after gallium-67 scanning. The observed effect is dependent on the radioimmunoassay used. False-negative results are observed with a modified Farr assay whereas false-positive results are noted in the millipore filter assay. These spurious values are the result of persistent radioactivity in the patients' sera after administration of 67Ga citrate.

Systemic lupus erythematosus. Contrasts and comparisons.

Systemic lupus erythematosus, a disease capable of exhibiting virtually any clinical manifestation, is discussed in detail and the findings are compared to those in other, presumably systemic lupus erythematosus-related connective tissue diseases. More emphasis has been placed on the clinical features than on the numerous laboratory manifestations. The conference begins and ends with a brief consideration of current concepts of pathogenesis and suggests some future investigational directions.

Cyclophosphamide or azathioprine in lupus glomerulonephritis. A controlled trial: results at 28 months.

Thirty-eight patients with diffuse glomerulonephritis of systemic lupus erythematosus were randomly assigned to add cyclophosphamide, azathioprine, or nothing to low-dose corticosteroid treatment and have been followed for a mean of 21/3 years thereafter. Of the 11 patients with unfavorable outcomes (8 deaths and 2 beginning hemodialyses), 2 occurred on cyclophosphamide, 4 on azathioprine, and 5 on prednisone only. Deaths due to infection occurred on the cytotoxics, while deaths ascribed to central nervous system lupus erythematosus occurred exclusively on prednisone only. Gradual deterioration of renal function was observed in all three groups, most frequently on prednisone only. Undesirable events, some due to drugs, were observed. At the time of reporting, the cytotoxic agents seemed to add marginally to the control of the disease; other treatment schedules should be evaluated.
